COUNSEL FOR APPELLANTS UNOPPOSED MOTION FOR EXTENSION OF TIME TO FILE OPENING BRIEF Appellants Cameron County Housing Finance Corporation (“CCHFC”) and Texas Workforce Housing Coalition (“TWHC”) file this unopposed motion seeking a 30-day extension of time, until and including January 16, 2026, to file their Appellants’ Brief.

1. The 425th District Court entered its final judgement on September 15, 2025.

2. CCHFC timely filed its notice of appeal on October 14. See Tex. R. App. P. 26.1. TWHC timely filed its notice of appeal on October 27, within 14 days of CCHFC’s notice of appeal. See Tex. R. App. P. 26.1(d).

3. The Clerk’s Record was filed on November 14, and the Reporter’s Record was filed on November 17, making Appellants’ opening brief due December 17, 2025. See Tex. R. App. P. 38.6(a).

4. Appellants respectfully request a 30-day extension of the deadline, to Friday, January 16, 2026. See Tex. R. App. P. 38.6(d).

5. This is Appellants’ first request for an extension of time. See Tex. R. App. P. 10.5(b)(D).

6. Appellants have good cause to request this extension.

-1- Appellants request this extension to allow their counsel an opportunity to fully analyze and brief the issues to be presented to this Court.

7. An extension is also necessary because of several scheduling conflicts in other matters involving Appellants’ counsel. In addition to preparing an opening brief in this case, Appellants’ counsel must also devote time to the following additional matters in December and January: In re Turner, No. 25-0114 (Tex.); In re Daniels, No. 25-0121 (Tex.); In re Peterman, No. 25-0129 (Tex.); In re Edwards, No. 25-0094 (Tex.); Alta Power, LLC v. General Electric International, Inc., No. 25-10774 (5th Cir.); In re AT&T Inc. Securities Litigation, No. 3:24-cv-01196 (N.D. Tex.); Blum v. AT&T Corp., No. 6:23-cv-01748 (W.D. La.); Hurley v. AT&T Corp., No. 3:25-cv-01755-JFS (M.D. Pa.); Drees v. AT&T Servs., Inc., No. 1:25-cv-00933-MN (D. Del.); American Beverage Association et al., v. Paxton, No. 6:25-cv-00566 (W.D. Tex.).

8. In addition, Appellants’ counsel presented oral argument before the Supreme Court of the United States on December 3, 2025, in Olivier v. City of Brandon, No. 24-993. Preparation for the oral argument further hindered the ability of Appellants’ counsel to devote substantial time to the briefing in this case.

-2- 9. Appellees do not oppose this request.

PRAYER For these reasons, Appellants respectfully request that this Court grant a 30-day extension of time, to Friday, January 16, 2026, to file their opening brief.

-3- Dated: December 10, 2025 Respectfully submitted,
